“…Debouck (1999) provided the number of available accessions for some species and reviewed their useful traits and the extent of chromosome pairing between interspecific hybrids. Despite the fact that the common bean chromosomes are extremely small, Mok and Mok (1977) at the prophase of somatic cells, and Cheng and Bassett (1981) at the diplotene stage of meiosis in pollen mother cells, identified all 11 chromosomes. Ashraf and Bassett (1986) induced translocations.…”

“…Literature data has listed additional applications of a detailed bivalent analysis, besides chromosome identification. Cheng and Bassett (1981) mention that, in the work of Brown (1949), chromatic and achromatic segments observed in tomato chromosomes are parameters for studies the process of chromosome condensation, pairing and chiasmata frequency. These same authors used these regions in bean chromosomes for condensation studies.…”

Chromosome analysis in pachytene has been considered a powerful tool in cytogenetic and evolutionary studies carried out in several plant species. Many morphological details of chromosomes can be observed during this stage, although overlapping of chromosomes may hinder the analysis. Considering this limitation, a new cytogenetic methodology was developed for maize meiotic chromosomes. This method consists of submitting the pollen mother cells (PMCs) to an enzymatic solution, which promotes PMC release from the anthers and subsequent digestion of the cell wall. The bivalents are mechanically released into the cytoplasm and spread out over the slide. In this slide preparation the chromosomes were isolated and spread over in the same plane of focus. The preservation of morphological traits of the bivalents, and the near complete absence of background or artifacts, resulted in high quality preparations, adequate for cytogenetic analysis. The obtainance of individual chromosomes allowed for the detailed analysis of the 10 maize bivalents. This analysis revealed additional data on the morphology and longitudinal differentiations of the chromosomes, facilitating their identification and morphological characterization.

“…The 22 chromosomes of P. vulgaris have already been karyotyped (Sarbhoy 1980, Cheng and Bassett 1981, Bairiganjan and Patnaik 1989. Although the small and low copy gene of Lb could be detected on one pair of chromosomes by in situ PCR-linked FISH using a short DNA fragment as a probe, the exact location of Lb gene on the chromosome could not be decided.…”
